DSA-1796-1 libwmf -- pointer use-after-free

Tavis Ormandy discovered that the embedded GD library copy in libwmf,
a library to parse windows metafiles (WMF), makes use of a pointer
after it was already freed. An attacker using a crafted WMF file can
cause a denial of service or possibly the execute arbitrary code via
applications using this library.
